TLDR
The results show that the photoinitiators and their UV-exposed counterparts affect intracellular AKT signaling, which can be used in conjunction with cell viability for cytocompatibility assessment of photoInitiators.
Abstract
Free-radical photopolymerization initiated by photoinitiators is an important method to make tissue engineering scaffolds. To advance understanding of photoinitiator cytocompatibility, we examined three photoinitiators including 2,2-dimethoxy-2-phenylacetophenone (DMPA), Irgacure 2959 (I-2959), and eosin Y photoinitiating system (EY) in terms of their effects on the viability of HN4 cells and expression levels of intracellular AKT and its phosphorylated form p-AKT. Our results show that the photoinitiators and their UV-exposed counterparts affect intracellular AKT signaling, which can be used in conjunction with cell viability for cytocompatibility assessment of photoinitiators.

Nonswelling Thiol–Yne Cross-Linked Hydrogel Materials as Cytocompatible Soft Tissue Scaffolds

TL;DR: This work describes a simple and effective way to control the swelling and degradation rate of nucleophilic thiol–yne poly(ethylene glycol) (PEG) hydrogel networks using two straightforward routes: using multiarm alkyne and thiol terminated PEG precursors or introducing a thermoresponsive unit into the PEG network while maintaining their robust mechanical properties.

Role for EPS8 in squamous carcinogenesis

TL;DR: A role for EPS8 in squamous carcinogenesis is supported using a model system and in vivo data and introduction of plasmids that direct synthesis of EPS8 short hairpin RNA into HN12 cells resulted in decreased EPS8 expression, which correlated with a decrease in their capacity to migrate and invade in vitro.

Risk genes in head and neck cancer: A systematic review and meta-analysis of last 5 years

TL;DR: The aim of this work was to identify risk genes related to the development and progression of squamous cell carcinoma head and neck (SCCHN) and do a meta-analysis of available estimates, showing no significant association between different allelic variants of Arg72Pro rs1042522 and SCCHN risk.

Encapsulation of osteoblast seeded microcarriers into injectable, photopolymerizable three-dimensional scaffolds based on d,l-lactide and epsilon-caprolactone.

TL;DR: The encapsulated UMR-106 cells did not show pyknotic nuclei which demonstrates that the photopolymerization and handling the viscous polymer/gelatin/microcarrier paste is not detrimental for the cells.

Formation of polymerized mixed heparin/albumin surface layer and cellular adhesional responses.

TL;DR: Platelet adhesion was markedly reduced on polymerized albuminated, polymerized heparinized, and copolymerized layers, whereas adhesive and proliferative potentials of endothelial cells, which were comparable to those of commercial tissue culture dishes, were observed on these surfaces.
